中国区域融合日照时数的高分辨率(10km)地表太阳辐射数据集(1983-2017)
收藏资源简介:
本数据集是一个包含34年(1983.7-2017.6)的全国高分辨率地表太阳辐射数据集,其分辨率为10公里,数据单位为W/㎡。该数据集是基于以ISCCP-HXG云产品为主要输入的全球高分辨率(3小时,10公里)地表太阳辐射数据集(1983-2017)上,通过地理加权回归方式,融合全国2261个气象台站日照时数反演的地表太阳辐射站点数据而生成的全国地表太阳辐射分布数据。验证并和其他全球卫星辐射产品比较表明,该数据集在长期趋势模拟上比GEWEX-SRB、CMSAF-CLARA-A2、ISCCP-HXG卫星辐射产品的精度要高。本数据可为陆地表面过程模拟的水文生态学的长期变化应用和研究中提供有利的数据支持。
This dataset is a national high-resolution surface solar radiation dataset spanning 34 years (July 1983 to June 2017), with a spatial resolution of 10 km and a data unit of W/㎡. It was developed based on the global high-resolution (3-hourly, 10 km) surface solar radiation dataset (1983–2017) that takes ISCCP-HXG cloud products as its primary input, via geographically weighted regression, by fusing in-situ surface solar radiation data retrieved from sunshine duration records of 2261 national meteorological stations. Validation and comparative analyses with other global satellite-based radiation products demonstrate that this dataset exhibits higher accuracy in long-term trend simulation compared to GEWEX-SRB, CMSAF-CLARA-A2, and ISCCP-HXG satellite radiation products. This dataset provides valuable data support for long-term change research and applications in hydroecology related to land surface process simulation.
